An envelope arrives from the council. Inside is a planning enforcement notice. Most people's first reaction is panic. Their second is to ignore it. Both are mistakes. An enforcement notice is serious — but it is not the end. You have rights, you have time, and in many cases you have more options than the council's letter implies.
A planning enforcement notice (EN) is a formal document issued by a local planning authority under Section 172 of the Town and Country Planning Act 1990. It alleges that a breach of planning control has occurred — either development carried out without permission, or a condition of a planning permission that has been breached. The notice sets out the allegation, the requirements, and the compliance period. The single most important thing to understand: the clock starts from when the notice is served on you, not when it was issued. Check the date carefully.
There is an appeal period — usually 28 days from the date of service — during which enforcement is suspended. If you appeal within that window, enforcement remains suspended until the appeal is decided. Missing this window means losing the right to appeal and the notice taking effect. If you are considering any ground of appeal at all, file the appeal to protect your position.
Ground (a): planning permission ought to be granted for the breach. Ground (b): the breach alleged hasn\'t occurred. Ground (c): what you did doesn\'t require planning permission — it\'s permitted development. Ground (d): the time limit for enforcement has passed — four years for operational development, ten years for material changes of use including residential use of land. Ground (e): the notice was not properly served. Ground (f): the requirements of the notice are excessive. Ground (g): the compliance period is too short. You can appeal on multiple grounds simultaneously.
Ground (d) — the time limit — is one of the most commonly misunderstood and most frequently lost grounds of appeal. The burden of proof is on you. You must demonstrate on the balance of probabilities that the breach began more than ten years before the enforcement notice was issued, and that the use has been continuous without substantial interruption throughout. What wins these appeals is contemporaneous, independent documentary evidence — utility bills, council tax records, vet invoices, delivery records. Personal statements without corroboration carry limited weight.
An enforcement notice is registered as a local land charge. It will appear on searches when the property is sold or remortgaged. If you appeal, the notice is suspended during the appeal period. Failing to comply after the compliance period has passed is a criminal offence — the council can prosecute, carry out the works, and charge you the cost.
Day 1–3: Read the notice in full and note the date of service. Day 1–7: Pull the full planning history for your site before instructing anyone. Day 1–14: Decide whether to appeal. Day 7–21: Gather documentary evidence of start date and continuity. Day 14–28: Instruct a planning solicitor for complex cases involving the 10-year rule, financial investment, or written assurances from a council officer. The legal arguments that matter most in these cases are not planning arguments — they require legal expertise.
